Я новичок в odata4j. Я пытаюсь запустить следующую программу, используя библиотеку odata4j v0.7:
import org.core4j.Enumerable;
import org.odata4j.consumer.ODataConsumer;
import org.odata4j.consumer.ODataConsumers;
import org.odata4j.core.OEntity;
import org.odata4j.examples.AbstractExample;
public class MyOdataTest extends AbstractExample {
public static void main(String[] args) {
ODataConsumer consumer = ODataConsumers.create("http://services.odata.org/OData.svc");
Enumerable<OEntity> qList = consumer.getEntities("Categories").execute();
}
}
Однако, когда я запускаю это в Eclipse, я получаю следующее исключение:

Пожалуйста, дайте мне знать, если я что-то упустил. Спасибо.
